[TheForge] drill bit stock

[Larry and Pat Brown]

Do you have an electric welder? They sell a rod for building up broken 
bolts to get them out, The rod burns in the center, under the coating and 
doesn't arc to the sides allowing you to puddle a new bolt shaft. Used them 
about 4 times with success. Would have used more but that was all that was 
in the sample pack. I would try to heat the bit first, then build it up to 
where vise grips will help
